The goal of this flask application is to fill a form, parse the data of the resulting form, launch a build, zip and send this build to the user.
Everything is working fine, but I want that once the form is filled, the user is redirected to a waiting page, if this is possible of course.
This is my code at the moment:
def create_and_download_build(form)
# Some parsing in the beginning of the function, the build etc...
os.system('tar -zcvf build.tar.gz dist/')
headers = {"Content-Disposition": "attachment; filename=build.tar.gz"}
with open('build.tar.gz', 'r+b') as data_file:
data = data_file.read()
response = make_response(render_template('waiting.html'), (data, headers))
return response
This is where this function is declared, in my _init__.py:
@app.route('/', methods=('GET', 'POST'))
def index():
form = MyForm() # MyForm is a class in which there is some
# wtform field (for example TextField)
if form.validate_on_submit(): # This is called once the form is validated
return create_and_download_build(request.form)
return render_template('index.html', form=form)
It doesn't work, I receive this error for the line in which I call make_response:
AttributeError: 'tuple' object has no attribute 'decode'
If I change make_response to : response = make_response((data, headers)), it will properly upload the file, but it will not render the waiting.html page.
Same if I change it to : response = make_response(render_template('waiting.html')), it will render the template, but it will not download the file.
Is there a method to do both action?
